Drew Barrymore 1 of 11

After becoming famous as a child star in the movie 'E.T. the Extra-Terrestrial,' Barrymore fell into a rebellious stage and reportedly began smoking cigarettes at age 9, drinking alcohol by age 11, smoking marijuana by age 12, and snorting cocaine by age 13. She entered rehab at age 13, and then again at 14 after a suicide attempt.
